Description
This reference standard supports related-substances testing and method development in line with ICH Q3A/Q3B guidance on impurity control, and is suitable for system suitability testing and forced-degradation studies.
CATO supplies Enalaprilat EP Impurity A (S,S-Isomer) (CAS 84023-58-5), a pharmacopoeial impurity reference standard (molecular formula C13H17NO4, MW 251.28 g/mol) used for the identification and quantification of trace impurities in APIs.
Enalaprilat EP Impurity A (S,S-Isomer) (C13H17NO4) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
CATO manufactures Enalaprilat EP Impurity A (S,S-Isomer) under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
